Kinematic and kinetic gait principal component domains in older adults with and...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.Objectives: Gait kinematic and kinetic changes have been identified in older adults, highlighting the need to explore the principal age-related components and how these are associated with functional disability. This study aims to perform a factor analysis, including gait kinematic and kinetic parameters in older adults to establish determinant gait domains. Additionally, this study aims to identify which domai...
Sit-to-stand and stand-to-sit kinematics in older adults with and without funct...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.Objective Sit-to-Stand (Sit-TS) and Stand-to-Sit (Stand-TS) transitions are essential daily movements affected by ageing and disability. This study aimed to explore related kinematic domains in older adults with and without disability. Methods A cross-sectional study including adults aged 60 years or older, with (n = 25) and without disability (n = 35). Comparisons between groups included task time, centre of m...
Kinematic Biomarkers of Functional Disability in Older Adults: Analysis of the ...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.The Timed Up and Go (TUG) test is used to assess mobility in older adults, but its reliance on completion time limits its insight into detailed movement patterns that could serve as early indicators of functional decline. This study aimed to identify lower limb and trunk kinematic biomarkers during the TUG test that distinguish between older adults with and without functional disability, emphasizing the potenti...
Principal component analysis of stair negotiation and floor transition kinemati...
Moreira, Juliana; Teles, Ivone da Silva; Cunha, Bruno; Félix, José; Guedes, Diana C.; Alves, Leonel A. T.; Santos, Rubim; Sousa, Andreia S PStair negotiation (ascending and descending) and transitions to level walking are complex motor tasks influenced by aging; yet the impact of functional disability on these changes remains underexplored. This study aimed to evaluate the lower limb joint positions, velocities, and the center of mass (CoM) displacement and velocity during stair negotiation and transitions in older adults with and without functiona...

Impact of workplace exercise program in the musculoskeletal symptomatology of w...
Mesquita, Cristina; Félix, José; Lopes, Sofia; Santos, Paula ClaraIn industrialization sector, musculoskeletal disorders are very frequent and can be considered as one of the main problems. They are associated with pain, discomfort, and functional limitations. Exercise programs can improve the symptomatology and daily life activities. Evaluate the impact of a 21-month exercise program on musculoskeletal symptoms reports of warehouse workers. This study was a randomized contro...
Interlimb coordination during double support phase of gait in people with and w...
Couto, Ana G. B.; Vaz, Mário A. P.; Pinho, Liliana; Félix, José; Moreira, Juliana; Pinho, Francisco; Mesquita, Inês; Mesquita Montes, AntónioThis study aims to identify differences between participants with and without stroke regarding the ipsilesional and contralesional lower limbs kinematics, kinetics, muscle activity and their variability during double support phase of gait. Eleven post-stroke and thirteen healthy participants performed 10 gait trials at a self-selected speed while being monitored by an optoelectronic motion capture system, two f...
Repeatability and temporal consistency of lower limb biomechanical variables ex...
Couto, Ana G. B.; Vaz, Mário A. P.; Pinho, Liliana; Félix, José; Moreira, Juliana; Pinho, Francisco; Mesquita, Inês AlbuquerqueReliable biomechanical methods to assess interlimb coordination during the double-support phase in post-stroke subjects are needed for assessing movement dysfunction and related variability. The data obtained could provide a significant contribution for designing rehabilitation programs and for their monitorisation. The present study aimed to determine the minimum number of gait cycles needed to obtain adequate...
Physical activity, readiness, and cardiovascular risk stratification in the pol...
Sousa, Andreia; Guedes, Diana C.; Félix, José; Pereira, Soraia; Santos, RubimThe aim of the study is to characterize physical activity (PA) levels and PA readiness as well as stratify cardiovascular risk among the population of polytechnics community members in the north region of Portugal, including students, academic teachers, and non-teacher staff. An online questionnaire about general sample characterization, PA level, and readiness was applied. Of the 717 respondents, 237 were acad...
